The Bose Quiet Comfort 45 headphones excel in comfort, with a perfect score, and they are well-suited for air travel and office use due to their exceptional noise cancellation capabilities. They are foldable and include a cable, which could be beneficial for wired use and when battery life runs out during long trips. On the other hand, the Bose QuietComfort Ultra Earbuds offer superior overall sound quality and are optimal for use during exercise thanks to their sweatproof certification and stability bands. They also have a feature set that includes wireless charging, low latency for gaming and watching TV, and an earbud design which is generally more portable than headphones. If you prefer in-ear comfort with advanced features, especially for active scenarios or mixed-media use, the Ultra Earbuds could be the better choice. However, for extended wear in quiet environments, such as long flights or workdays, the Quiet Comfort 45 might serve you better with their top-notch comfort and noise isolation. Give Feedback

"If you want a set of wireless over-ear headphones you can put on, deploy noise-cancelling on your commute or at your desk and largely extinguish the outside world for up to 24 hours, the Bose QC 45 has the edge over most of the competition at the price."

"Bose put the time in to fix the major issues with the previous earbuds, and the Bose QuietComfort Ultra Earbuds are very befitting of its price point. While you might be tempted to save a few bucks and go with the Bose QuietComfort Earbuds II on sale, fight the urge. There are enough upgrades here to justify the newer model."
